The first scheme is a (one-time) uncloneable encryption scheme, as considered in the work of [1]}. We denote this scheme by \(\mathsf {otUE}\) .
An instantiation of such a scheme is

The second scheme is a post-quantum encryption scheme guaranteeing reusable security but without any uncloneability guaranteesAs an example, we could use Regev's public-key encryption scheme [2]}.. We denote this scheme by \(\mathcal {E}\) .
